git-bump ambiguous name

Currently, if there are two submodules and the name of one submodule is a substring of the second submodule, the script will fail due to name ambiguity. Example:

• submodules VTK and VTKStreaming
• git bump VTK master returns "Submodule name ambiguous, aborting" because

config="$( git config --local --get-regexp "submodule\..*$submodule.*\.url" )"

in line 64 of git-bump matches both of them .

How about instead of allowing 0 or more characters after $submodule, require at least a path separator / or . ?

config="$( git config --local --get-regexp "submodule\..*$submodule[\/|\.]+.*url" )"

this solves the above issue while still allowing to use directories to refer to submodules e.g. for

submodule.ThirdParty/IceT/vtkicet.url

both IceT and icet will work.
