revset: support raw string literals This adds support for r'...' and r"..." as string literals. Strings with the "r" prefix will not have their escape characters interpreted. This is especially useful for grep(), where, with regular string literals, \number is interpreted as an octal escape code, and \b is interpreted as the backspace character (\x08).

tests: fold darcs test repository into a bundle

tests: avoid checking the exitcode of false Solaris false returns 255 instead of 1, so we remove one unneeded instance and replaces another with (exit 1) as suggested by Brodie Rao.

test-rename: accept solaris diff Solaris diff gives @@ -1,1 +1,1 @@ instead of @@ -1 +1 @@

test-subrepo-svn: restore expr functionality for solaris Cleanup in 22f3353bcc36 removed a syntactically incorrect and apparently unnecessary escape of / for expr - but solaris needs it.

test-serve: fix test for binding to low named port on solaris Solaris do not know the service called http, so we use echo instead. Trying to define KILLQUIETLY when running the hgserve function didn't set the value within the function. Now we set the variable before calling the function.

templater: add a few comments.

incoming/outgoing: Fix recursion on sub repositories Incoming and outgoing are fixed so they go through the whole three of repositories instead of only visiting first level of sub repositories.

tests: added a short description to issue numbers Many tests already had a short line to describe what IssueXXX is about. I find that quite useful when reading a test.
