Subject: libfstools: optimize building directory string for glob
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Ffstools.git;a=commitdiff_plain;h=2a9a6ea4ac221f913ea318d7ac17ff2c31bdf5c2

libfstools: optimize building directory string for glob

glob should handle paths like /foo/bar//* so we probably don't need this
extra check & code.
