[SVN] r12059 (R)

[Hans-Jörg Bibiko]

• run the BASH command associated to the macro "Show Function Usage" in a background task to avoid waiting for it if user has installed lots of packages; i.e. the user has the chance to wait for the tooltip or to simply type further

[maybe an interesting approach for other bundles as well]

Changed:
U   trunk/Bundles/R.tmbundle/Macros/Show Function Usage + Insert “(”.tmMacro
