Now that Ant plugin is outside Jenkins core, changing the message (was done in 76edfd3a) caused this regression.

exposed data about installed plugins, installable plugins, update center jobs, etc., to the REST API

With a textarea the likelyhood of the value exceeding the maximum safe length for a GET request (which IE8/9 pegs to somewhere between 2k and 5k depending on the context) is too great as to not provide for the checkMethod to be specified in order to allow for POST requests to be used in place of GET requests for form validation

Fix typo: 'choosen' should be 'chosen'.

Typo in custom workspace help tip

Add a new overload method to list files that include the files that ant excludes by default.

Previously, the untar code tries to set the last modified time and mode
on every untarred file.  However, if the tar contains a broken symlink,
or a symlink that points to a file that has not been untarred yet, the
time/mode setting would fail on the broken symlink.

Symlinks don't have meaningful modified times or modes of their own, so
only set these values on non-symlinks.

Rename the file "a" in the test to expose the bug.
