Subject: gitweb.js: fix padLeftStr() and its usage
X-Git-Url: https://git.ladys.computer/Gitweb/commitdiff_plain/67c4b962f002a1cec72af35bfbec00455d8a9b0e2c250d9c0717f9c29f371bfd?ds=sidebyside

gitweb.js: fix padLeftStr() and its usage

It seems that in Firefox-3.5 inserting &nbsp; with javascript inserts the
literal &nbsp; instead of a space. Fix this by inserting the unicode
representation for &nbsp; instead.

Also fix the off-by-one error in the padding calculation that was
causing one less space to be inserted than was requested by the caller.
