The previous code would correctly parse strings including quotation
marks (") or backslash (/), but the tests when creating the export
includes them in the final string. This prevents exporting paths
with embedded spaces, for example "/exports/with space". Trying
results in log lines resembling:
mountd[1337]: bad exports list line '/exports/with\ space':
/exports/with\ space: lstat() failed: No such file or directory.
Turns out that when creating its exports list, zfs escapes strings
in a format compatible with vis(3). Since I expect that zfs sharenfs
is the dominating use case for generating an exports list, use
strunvis(3) to parse the export path. The result is lines like the
following allowing spaces:
/exports/with\040space -network 192.168.0 -mask 255.255.255.0
A man page update will be done as a separate commit.
