[issue1434] [PATCH] sh(1): Implement $LINENO built-in variable

["Stathis Kamperis \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Stathis Kamperis <ekamperi@gmail.com>:

Salute.

Regarding sh(1):

LINENO
    Set by the shell to a decimal number representing the current sequential
line number (numbered starting with 1) within a script or function before it
executes each command. If the user unsets or resets LINENO , the variable may
lose its special meaning for the life of the shell.

I attach a patch, obtained from FreeBSD, that implements $LINENO.
I'm running a system with the patch applied, but I need to test it more.

Unless no one objects, I'll push it in 161 hours and 48 minutes.

Cheers,
Stathis

PS. I'll also obtain the "Fix checking if a variable name is LINENO." patch as
well (SVN Revision 179387). But first thing first.
