#21 -r does not work for files with special characters

[John Williams]

For example:

$ echo 'test' > pound#pound
$ /usr/bin/lpr -Pmyprinter -r pound#pound

Warning - Error unlinking 'pound_pound' - No such file
or directory

In lpr.c (version 3.8.26), Check_files, line 1206
Clean_meta is called on a char* which still points to
the original filename in Files.list[0], thus corrupting
the filename and causing the error when unlink is
attempted later.

The attached patch fixes the problem by safestrdup-ing
the string before calling Clean_meta.
