Move 'findrenames' code into its own file. The next few patches will increase the size of the "findrenames" functionality. This patch simply moves the function into its own file to avoid clutter building up in 'cmdutil.py'.

acl: cleanup module docstring - removed implementation detail about how the group information is obtained - fixed some language, better consistency - fixed bad comment in hgrc example

acl: fix ReST syntax in docstring

relink: removed unneeded local variable

test-acl: grep for $HGTMP, not /tmp/

dispatch: don't mangle ImportError abort messages Previously, Mercurial assumed that the last word of the string representation was the name of the moduled that was imported. This assmption is incorrect, despite being true for the common case of an exception raised by the Python VM. For example, hgsubversion raises an ImportError with a helpful message if the Subversion bindings were not found. The final word of this message is not meaningful on its own, and is never the name of a module. This patch changes the output printed to be a simple stringification of the exception instance. In most cases, this will be `abort: No module named X!' rather than `abort: could not import module X!'. No functionality change; all tests pass.

relink/progress: correctly handle the no file to relink case
