Re: Improvements to the gcc completion script

Does anyone know a way to prevent '--' from being split in 'partial word completion'?

Suppose a cmd accept --baz and -foo-bar as options, and match-spec
r:|-=* r:|=*
is in use. Then 'cmd --b<TAB>' will offer both options.

Is it possible to complete -foo-bar for -f-b<TAB> but only --baz for 'cmd --b<TAB>'?
(this is ralted with [2] below; [1] is cosmetic)

On one of my Mac, in which Xcode.app is installed, 'xcrun --show-sdk-path' gives
and not only Xcode but also clang invoked from the command line uses this directory.

But hitting a few more TABs will give you --optimize.

It may be annoying for you, but I believe there are many users who are accustomed
to using 'partial word completion' and removing it is not a good idea.

Match-spec 'r:|[_-][^-]=* r:|=*' may work better but not perfect.
