Make shortlog the default page in hgweb

hgweb: improve shortlog formatting shorten author with |person don't shrink font (default font is presumed to be preferred reading size) set widths based on font ems rather than page percents.

strip: move strip code to a new repair module

strip: simplify bundle helper

strip: pull core strip logic into its own function

unbundle: accept multiple file arguments update test-bundle for multiple unbundle support

convert: handle new cvsps with Tags: and multiple tags.

cat: return an error on failure

tests: add merge test for changeset 9fe267f77f56 When all the files in a directory are moved somewhere else, and new files are added in changesets of the local branch, a subsequent pull and merge shouldn't rename the locally added files too.

purge: add the clean alias inspired by git-clean and svn-clean

mercurial.el: ignore errors on hg-after-save-hook() Don't signal an error even if running hg command fails. Otherwise, succeeding hooks won't be called.

mercurial.el: change default log range to tip:0 If the tip revision is smaller than hg-rev-completion-limit (defaults to 100), "hg log -r tip:-100" fails. Since performance does not differ between "hg log -l 50 -r tip:0" and "hg log -l 50 -r tip:-100" even on large repository, default range can be changed from "tip:-100" to "tip:0" without any drawbacks.

Command in doc comment is now on a single line, fixed after previous formatting broke it.

purge: don't delete ignored files if --all is not specified
