i18n: translate abort messages
I found a few places where message given to abort is
not translated, I don't find any reason to not translate
them.
hgweb: display blamed revision once per block in annotate view
I.e. when a revision blames a block of source lines, only display the
revision link on the first line of the block (this is identified by the
"blockhead" key in annotate context).
This addresses item "Visual grouping of changesets" of the blame improvements
plan (https://www.mercurial-scm.org/wiki/BlamePlan) which states: "Typically
there are block of lines all attributed to the same revision. Instead of
rendering the revision/changeset for every line, we could only render it once
per block."
hgweb: highlight data of the current revision in annotate view
* Distinguish the /annotate/<revision>/<file>#<linenumber> link when it would
lead to the current page (i.e. <revision> is the current revision) (style it
gray and undecorated). This indicates more clearly that this is a "dead-end"
in blame navigation.
* Display lines changed in current revision in green.
bashcompletion: show available command-line switches for aliases
When auto-completing hg commands, aliases are listed, but not the available
switches for an alias, because `HGPLAIN=1` filters these out. Add a
`HGPLAINEXCEPT=alias` exception to resolve this.
We make heavy use of aliases that drive hg log with custom revsets, sorting and
the -G switch, but want our users to be able to auto-complete any additional
command-line switches.
