Adds a template function that executes a revset and returns the list of
revisions as the result. It has the signature 'revset(query [, args...])'. The
args are optional and are applied to the query string using the standard
python string.format(args) pattern. This allows things like:
'{revset("parents({0})", rev)}' to produce the parents of each individual
commit in the log output. If no args are specified, the revset result is
cached for the duration of the templater; so it's better to not use args if
performance is a concern.
By itself, revset() can be used to print commit parents, print the common
ancestor of a commit with the main branch, etc.
It can be used with the ifcontains() function to do things like
'{ifcontains(rev, revset('.'), label(...), ...)}' to color the working copy
parent, to color certain branches, to color draft commits, etc.
Transform the backslashes to slashes on windows, because they are eaten up by
the shell. (Similar as done in test-check-pyflakes.t.)
This test will not produce a traceback on windows anymore. But the test still
fails because the detected mixed imports differ.
This patch backs out dbcb4de20d06, which caused test-module-imports.t to
be skipped when the test was run using virtualenv. Since the test now
passes when using virtualenv, the skip is no longer necessary.
