Subject: include/strutils: Add startswithpath()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=10f0de325d016d7f0fcdbb07372292bd406fdb96;p=thirdparty%2Futil-linux.git

include/strutils: Add startswithpath()

This is similar to startswith() but checks if the prefix is a complete
path or a complete subdirectory (needs to end with '/').
