hgweb: align entries in "changelog" and "revisions" pages of "spartan" style Before this patch, each log entries in "changelog" and "revisions" pages of "spartan" style are not aligned by column, because: - each log entries are separated "<table>" entries, and - there are no fixed "width" information for each "<th>"/"<td>" entries This patch aligns entries in "changelog" and "revisions" pages of "spartan" style by: - adding 'label' class to '<th>' for 'age' information, and - setting 'width' of '<th class="label">' with fixed size 'class="age"' is not used for this purpose, because it is also used to set "bold" font-weight "16em" seems to be wide enough to show date information fully, when web browser disables (or doesn't support) javascript.

hgweb: show revisions and hashes gotten from changelog in "comparison" page Before this patch, revision numbers and hash values in "comparison" page are gotten from not changelog but filelog. Such filelog information is useful only for hgweb debugging, and may confuse users. This patch shows revision numbers and hash values gotten from changelog in "comparison" page.

hgweb: show as same parents as "hg parents -r REV FILE" in pages for file Before this patch, "parents" in pages for file doesn't show as same parents as "hg parents -r REV FILE", when the specified file is not modified in the specified revision. For example, it is assumed that revision A, B and D change file "f". changelog (A) ---> (B) ---> (C) ---> (D) filelog "f" (x) ---> (y) ------------> (z) "/file/D/f" invokes "webutil.parents()" with filectx(z) gotten from changectx(D), and it returns changectx(B). This is as same result as "hg parents -r D f". In the other hand, "/file/C/f" invokes "webutil.parents()" with filectx(y') gotten from changectx(C), and it returns changectx(A), because filectx(y') is linked to changectx(B), and works like filectx(y) in some cases. In this case, revision B is hidden from users browsing file "f" in revision C. This patch shows as same parents as "hg parents -r REV FILE" in pages for file, by making "webutil.parents()" return: - "linkrev()"-ed revision only, if: - specified context instance is "filectx" (because "webutil.parents()" is invoked with changectx, too), and - (1) the revision from which filectx is gotten and (2) the one to which filectx is linked are different from each other - revision gotten from "ctx.parents()", otherwise
