PATCH: further support for <import>s in ant completion

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

The following patch is an addition to Konstantin Sobolev's recent patch
for handling targets from imported files. Turns out that if the imported
files are specified using a relative pathname, that path is resolved
relative to the location of the original build.xml. The fix involves
using cd before sed in the subshell.

Imported files from imported files don't work but _ant has the
alternative method enabled with the call-command style. It isn't default
because it is too slow and, Konstantin tells me, ant -projecthelp only
lists targets with a description.
