TODO

@@ -1,45 +1,44 b''
 General:
 - Better documentation
 - More regression tests
 - More specific try/except.
 - less code duplication, more code in the right places
 - python 2.2 support
 - better import support
 - export to git
 - Add standard files: AUTHORS, CREDITS, ChangeLog? What else?
 - Code cleanup: apply http://python.org/peps/pep-0008.html
 
 Core:
 - difflib creating/removing files (fixed except dates: should be epoch)
 - directory foo.d or foo.i with existing file foo (use some quoting?)
 - get various options from hgrc (e.g. history always -v, tip always -q)
 - better push support (hack exists)
 - hg over ssh:// and https://
 - commit mailinglist/trigger/hooks
 
 Commands:
 - hg status <filename>: file rev, changeset rev, changed, added,
   deleted, sha-1
 - select to pull a subset of the heads
 - commands.py: number of args too much magic (e.g. in patch())
 - automatic pull fallback to old-http://
 - hg init|pull http://example.com doesn't say that no repo was found
 - hg annotate -u and hgweb annotate with long $EMAIL
-- hg -v history doesn't show tkmerge as modified (removed).
 - hg pull default in a subdir doesn't work, if it is a relative path
 - optionally only show merges (two parents or parent != changeset-1, etc.)
 
 Web:
 - show tags in hgweb
 - show parent changeset number in hgweb
 - optionally only show merges (two parents or parent != changeset-1, etc.)
 - one hgweb with many repos (another script)
 - hgweb tip link too verbose
 - hgweb: deliver static files (e.g. favicon, stylesheets)
 - hgweb personalization: timezone (display/change), display of
   features
 - hg export 240 shows -tkmerge (good), hgweb does not (bad).
 - some web servers think hgweb.cgi.[di] is a CGI script with old-http://
   (use quoting (see foo.d in Core) or document server configurations?)
 - link children in hgweb
 - search field searching in descriptions, file names, what else?
