Files that match *.mk and *.mak as well as GNUmakefile are now included in the ack filetype 'make' (issue 88).
Added RSpec's .spec type to the --ruby list.
ENHANCEMENTS
Updated the README to Markdown format. Thanks to Mark Szymanski for the idea.
Added docs for -r, -R, --recurse options.
Added new switch --color-lineno and environment variable ACK_COLOR_LINENO, which allow setting the line number color. (Marq Schneider)
Added option --show-types to output the types that ack considers a file to have. (Torsten Blix)
'ack --count --no-filename regex' doesn't output a list of numbers but a sum of all occurences. This is NOT what grep does but is the more sensible behavior.
FIXES
Fixed ack misbehavior when using --match or not specifying a regex:
ack --match Sue cat foo | ack --perl
Fixed issue 74: analog to grep, 'ack --count regex file' now only outputs the number of found matches, if only one file is given.
Fixed issue 76: Giving both --line and a regex (with --match) now leads to an error. The same is true for -f or -g in conjunction with --match. (Torsten Blix)
Fixed issue 80: Piping into ack --count now works as expected. ack always returned 0 when piped into, no matter how many matches where found. (Torsten Blix)
Fixed issue 81: .ackrc now ignores leading/trailing whitespace. (Torsten Blix)
