* lisp/eshell/esh-module.el: Don't require eshell.
* lisp/eshell/esh-opt.el: Don't require esh-ext at top-level.
(eshell--do-opts, eshell-show-usage): Require it here instead.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
The new buffer syntax '#<buffer-name>' is equivalent to '#<buffer
buffer-name>'. Remove `eshell-buffer-shorthand', as it is no longer
needed (Bug#19319).

(eshell-get-target): Remove shorthand-specific code.
* lisp/eshell/esh-arg.el (eshell-parse-special-reference): Parse
'#<buffer-name>'.
Fixes: debbugs:8531
* lisp/eshell/esh-arg.el (eshell-parse-argument-hook): Update comment.
(eshell-parse-backslash): Return escaped character after backslash
if it is special. Otherwise, if the backslash is not in a quoted
string, ignore the backslash and return the character after; if
the backslash is in a quoted string, return the backslash and the
character after.
* test/automated/eshell.el (eshell-test/escape-nonspecial)
(eshell-test/escape-nonspecial-unicode)
(eshell-test/escape-nonspecial-quoted)
(eshell-test/escape-special-quoted): Add tests for new
`eshell-parse-backslash' behavior.
