bin/repl: match as whole-word text (like SQL identifier): documented that this is a generalization of lib/sql_gen.py map_expr() to work on entire source files

bin/repl, lib/sql_gen.py Expression transforming: documented that this can also be done in Postgres with expression substitution (wiki.vegpath.org/Postgres_queries#expression-substitution)

fix: bin/repl: text mode (whether all patterns are plain text) should default to on, not off, if matching entire cells in a spreadsheet

fix: bin/repl: don't consider uppercase SQL keywords to indicate that a word is in a sentence

bugfix: bin/repl: only use excluded_prefix_re/excluded_suffix_re in text mode (used in renaming columns in SQL scripts), to prevent the special coding for column renames from also affecting regular regexp/word replacements

bugfix: bin/repl: text mode: also don't match if it's part of a '-'-separated identifier

bugfix: bin/repl: text mode: also don't match if it's a word in a sentence

bugfix: bin/repl: text mode: turned off the suffix matching, because there are cases where a mapping adds a suffix which would cause the same replacement to be performed repeatedly

bin/repl: text mode: exclude prefixes that should not cause replacement, to avoid doubling leading *

bin/repl: text mode: also match w/ suffix (eg. _verbatim)

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

bugfix: bin/repl: text mode: repurpose this to match SQL identifiers, for use by inputs/input.Makefile %/postprocess.sql. %/postprocess.sql is the only place currently using this mode, so this will not affect other scripts.

bugfix: bin/*: spell out [:alnum:] as [a-zA-Z0-9] because Python unfortunately doesn't support character classes

bin/*: replaced confusing regexp constructs involving \W inside [] with the much clearer explicit character class [:alnum:] . this avoids adding or subtracting from an inverted class in order to reach a subset of the corresponding positive class, because the subset can just be named explicitly instead.

bugfix: bin/repl: doesn't make sense to use other chars in a [^\W_] regexp, because they will have no effect since \w doesn't include the other chars to begin with. this is a result of confusion with the ^ and \W double negative.

bin/repl: added unescape_html() filter function, which can be specified as the replacement string

bin/repl: support Unicode characters in the matched portion of the string

bin/repl: skip header instead of parsing it, since its columns are not used. this also allows using just a blank line as the header when the column names are not important.

repl: :-prefixing of words to form vars: Fixed bug where : must be matched as a lookbehind assertion, not a capturing group, because the provided regexp itself or its replacement may reference capturing groups, which it expects to be numbered starting with 1

repl: text mode: Also match "vars" with the term prefixed by ":". Consider .- to be word characters. Only match a word when preceeded by whitespace or CSV field start characters.

repl: column mode: Removed parsing and checking of column name, which prevents using repl for general-purpose regexp/word replacement

repl: Support treating all patterns as plain text (non-regexp)

ch_root, repl, map: Use new maps.col_info() instead of parsing col name manually. This allows maps with prefixes containing ":" to be supported, without the ":" being misinterpreted as the label-root separator.

repl: Removed automatic case-insensitivity because Python apparently only supports turning on case-insensitivity via (?i) but not off via (?-i) (as Java does)

repl: All regexps are by default in multiline and ignore case mode

repl: When matching words, treat _ as word boundary and ignore case.

repl: Process whole file as one string so that regexps can match EOF for appending

Renamed util to bin

Moved everything in scripts to root. inputs_Makefile: Don't run "all" when installing.

repl: Added support for blank lines. Only add whole word regexp code to inputs w/o any regexp metachars.

repl: Fixed bug in reading arguments

repl: Don't add whole-word regexp for inputs that already have regexp metachars

Added repl to perform replacements on a spreadsheet or file
