A series file for quilt has a valid syntax of:
fixes/autoconf.diff -p1
fixes/doc-html-local-css.diff -p1
fixes/gnu-inline.diff -p1
However, with the current way that a series file is handled, it will
error out because the -p1 is tried as a file. This is because in the
for loop that iterates the files, we only look for comment lines. Then
each line is used within a bash for loop which uses spaces a
delimiter. In order to fix this, we should only use the string that
comes before a space in the series file.
Note that the format allows for any arbitrary depth to the -pN field.
But since we'll have only one package with -pN fields, and all will be
-p1, we for now always assume -p1. This will have to be fixed whenever
we get a package with other values.
