man invocation not portable

[petere]

The invocation of man in misc/ext.d/text.sh.in is not portable. BSD man commands do not take the -l option to show a man page by file name. (Instead, just give the file name, no option necessary.)

As a result, viewing man pages with mc does not work on these platforms.

Distributions are working around that:

• ​https://github.com/Homebrew/homebrew/pull/42176
• ​https://svnweb.freebsd.org/ports/head/misc/mc/files/patch-misc__ext.d__text.sh.in?view=markup&pathrev=382039

man

[and]

man option -l was used to ensure that last parameter interpreted as (local)file and not as page.

man -P cat file.name
No manual entry for file.name
$ man -P cat -l file.name
man: file.name: No such file or directory
$ man -P cat /file.name
man: /file.name: No such file or directory
No manual entry for /file.name

for man-db (which provide -l option) this option is not required at all
because man-db detects if last parameter is a file
and mc helper calls by full pathfilename always.

So let's get rid of not-at-all supported -l option
