test-gendoc: require gettext If the gettext utilities aren't installed, there is no way to make the translations. This causes the gettext client to fall back to the untranslated message, which triggers "** NOTHING TRANSLATED **" errors and a test failure.

hgweb: use css margin instead of empty <p> before diffstat table The <p> elements were used to create an empty space between the diffstat link and the diffstat table, but they don't have any semantic meaning, so it is better to use css instead. Default margins for <p> elements can differ depending on the browser, but usually the margin is 1em (exceptions are IE 6 and 7 with 14pt, which is comparable). The css rule sets top margin to 1em. This change is a "better version" of 70cfa7e1611b, where <p> elements were simply properly closed.

hgweb: use css margin instead of empty <p> before <div class="atom-logo"> The <p> elements were used to create an empty space between the last menu item (i.e. "help") and the atom feed icon, but they don't have any semantic meaning, so it is better to use css instead. The css rule uses top margin of 10px, which is equal to the top margin of the menu blocks ("help", "changeset, browse", etc). Previously, with <p> elements, the margin wasn't set explicitly and was browser-dependent. This change is a "better version" of 70cfa7e1611b, where <p> elements were simply properly closed.

error: update docstring on ParseError It's now used by revsets and filesets.

dispatch: consolidate formatting of ParseErrors

error: store filename and message on LookupError for later It may be useful to be able to get to the failed path and the underlying error message when catching a LookupError, so let's make them accessible.

bundle2.unbundlepart: implement seek() This implements a seek() method for unbundlepart. This allows on-disk bundle2 parts to behave enough like files for bundlerepo to handle them. A future patch will add support for bundlerepo to read the bundle2 files that are written when the experimental.strip-bundle2-version config option is used.

bundle2.unbundlepart: tell() implementation Keep track of how many bytes we've returned from read(); fairly straightforward.

bundle2.unbundlepart: keep an index of chunks and their locations In order to make unbundlepart seekable, we need to keep a record of where the chunks are so that we can go back to the correct point.

bundle2.unbundlepart: raise payloadchunks from a closure to a method In a future patch, seek() will need to make a new chunk iterator for the stream; this places it somewhere it can be called multiple times.
