i18n: use encoding.colwidth() for correct column width Some encoding and language combinations (e.g.: UTF-8 and Japanese) cause encoding characters into sequence of bytes more than column width of them. So, encoding.colwidth() should be applied instread of len() on i18n strings. In addition to it, formatting by '%*s'/'%-*s' also uses "number of bytes" to calculate space padding size, and should be fixed, too.

log: slowpath: do not read the full changelog When in the slowpath, we are examining _all_ changesets in revs. We need to order reads so they happen increasingly for I/O performance. Increasing windows were used to read changelog backwards in a windowed manner, reading the changelog forward inside each window. But since no revision range was specified, it was equivalent to reading the full changelog, even if a single revision was passed to the commandline. When --removed is used, we _need_ to scan all changesets, but if we're only looking for file patterns, this is not necessary and we can stick to the revspec that was given to us.

log: remove increasing windows usage in fastpath The purpose of increasing windows is to allow backwards iteration on the filelog at a reasonable cost. But is it needed? - if follow is False, we have no reason to iterate backwards. We basically just want to walk the complete filelog and yield all revisions within the revision range. We can do this forward or backwards, as it only reads the index. - when follow is True, we need to examine the contents of the filelog, and to do this efficiently we need to read the filelog forward. And on the other hand, to track ancestors and copies, we need to process revisions backwards. But is it necessary to use increasing windows for this? We can iterate over the complete filelog forward, stack the revisions, and read the reversed(pile), it does the same thing with a more readable code.

context: use os.lstat instead of os.stat to fetch file size When file is a link, we want the size of the link itself, not the size of the file it points to.
