cmdutil.walkchangerevs: use '-1:0' instead ot 'tip:0' This avoids a possibly expensive tag lookup.

revlog.revision: avoid opening the datafile without need. If there's no inline data, revlog.revision opens the data file every time it's called. This is useful if we're going to call chunk many times, but, if we're going to call it only once, it's better to let chunk open the file - if we're lucky, all the data we're going to need is already cached and we won't need to even look at the file.

convert: document splicemap, allow setting of multiple parents

merge backout

Backed out changeset b913d3aacddc (see issue971/msg5317)

Simplify utils.walkrepos().

Fix bad behaviour when specifying an invalid date (issue700) commit (aborts _after_ typing in a commit message) backout (aborted after the initial revert) tag (edited .hgtags and couldn't commit) import (patch applied, then commit fails) qnew (aborts on bad dates, but writes any valid date into the # Date header) qrefresh (like qnew) sign (like tag) fetch (merge, merge, merge, merge, abort)

Report filenames with disallowed characters as suggested by Mika Eloranta (see issue671)

hgweb: Quote filenames when downloading raw files.

hgweb: Pass only filename instead of full path when downloading raw files. Before this patch "filename=foo/bar" was sent and e.g. Firefox offered to save the file as "foo-bar" instead of just "bar".
