paper: preserve whitespace on description instead of adding breaks
This preserves the indentation of text in the changeset description.
This is useful for example for descriptions containing command line
use case examples like:
$ hg -q heads
13934:
648a834cca14
13912:
71ea5b2b9517
Without this patch, such space-char indented text was just left aligned.
revsets: preserve ordering with the or operator
This is valuable because now revsets like 'bookmarks() or tip' will
always show tip after bookmarks unless tip was itself a bookmark. This
is a somewhat contrived example, but this behavior is useful for
"where am I" type aliases that use log and revsets.
hgweb: set minimum number of revision to display to 1 when revcount is 0
When revcount goes to 0 nothing is displayed in hgweb. This patch sets revcount to max(revcount, 1).
localrepo: don't add deleted files to list of modified/added files (
issue2761)
If a file is deleted (rm, not 'hg rm') from the working dir
an attempt to run 'hg diff -r X', with the file being present in X will
cause an abort.
We didn't check if the file has been deleted from the working dir
and later on tried to open it to compare with the one from X, causing the abort.
This fix adds that check. Consequently, no output will be returned.
