filemerge: better handling of failing remove of temporary files We have seen some failures on Windows that could seem like the unlinks of temporary files were failing. That could perhaps be because the merge tool somehow still held the files open. Instead of the bare bone os.unlink, use our util.unlink with special rename/retry handling on Windows.

contrib: remove mergetools.hgrc premerge=False for Beyond Compare and Araxis There can be good reasons to disable premerge no matter which merge tool is used. Most tools will do just fine without premerge and handle the simple merges more or less automatic and silent. We _could_ thus disable premerge for most tools. But without premerge, the merge tool will be launched for each file - that makes it a slow and expensive process to perform big simple merges. It is thus better to consistently stick to the default premerge=True. The mergetools.hgrc configuration for most tools implicitly use the default premerge=True but Araxis and the Linux entry for Beyond Compare had premerge=False. These lines has been removed. These settings were introduced by 6b354a763617 without further explanation of why they should be good. (We have seen some crashes on Windows with Araxis where a merge failed after a lot of Araxis flashing. I haven't been able to reproduce it and do not know exactly what happened. Enabling premerge avoids the problems.)

obsolete: add '%' specifier to the format string to avoid TypeError at runtime Mapping operation on the format string not including any '%' specifiers causes TypeError at runtime.

check-code: detect "% inside _()" when there are leading whitespaces Before this patch, "contrib/check-code.py" can't detect "% inside _()" correctly, when there are leading whitespaces before the format string, like below: _( "format string %s" % v) This patch adds regexp pattern "[ \t\n]*" before the pattern matching against the format string. "[\s\n]" can't be used in this purpose, because "\s" is automatically replaced with "[ \t]" by "_preparepats()" and "\s" in "[]" causes nested "[]" unexpectedly.
