Subject: file.c: Fix a file descriptor leak in readfile()
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=7fe652ab5738717ba443ae9de2b8f437103fd71b

file.c: Fix a file descriptor leak in readfile()

In file.c::readfile() the file was being opened once at fd declaration
time and then again a few lines later and only being closed once. Remove
the open() at fd declaration time leaving the later one where the fd check
is done.
