util.rename: use temporary file name for rename-targets on windows Use a temporary file name as target for a forced rename on Windows. The target file name is not opened at any time; just renamed into and then unlinked. Using a temporary instead of a static name is necessary since otherwise a hg crash can leave the file lying around, blocking future attempts at renaming.

churn: use .hgchurn in repo root as default map file

win32text: add copyright header

patchbomb: add copyright and license header

highlight: add copyright and license header

convert: add copyright and license headers to back-ends

Reproduce crash where synthetic revs break merge detection (issue1578). (The fix for this was committed as 9bbcfa898cd3.) Slightly edited by Patrick Mezard <pmezard@gmail.com>

convert/svn: ignore composite tags Tools like cvs2svn generate tags made of files coming from different revisions from different branches. This is not supported by Mercurial, and it slows down the conversion a lot. Ignore them. See bacula@4082 for a sample.

Merge with crew-stable

convert/svn: keep latest and not oldest tag value
