[PATCH] Treat single space table entry names specially, i.e., reject them

[Erik Auerswald]

Hi,

some tables used with "genget()" use table entries with a single space
character as entry name for special purposes, i.e., as empty lines or
comment lines.  Thus an entry with name " " is not intended as a valid
table entry, but "genget()" does not treat those entries differently from
valid antries.  It should instead reject any attempt to get the entry to
the name " ".

Rejecting to get the table entry for " " would have masked that both
setcmd() and unsetcmd() are not able to handle those table entries.
Thus this rejecting the name " " can be seen to improve robustness.

The attached patch "inetutils-libtelnet-genget-no_space_command.patch"
implements this.

[The genget() function requires "name" to be a valid C string already.]

Thanks,
Erik
