I am loading the attached bash file but imenu is not showing all the declared bash functions in the file, it only shows PF(), PFB(), PF2(), and pfm.  This has also the consequence of not displaying all functions in speedbar.

File is attached.

The problem lies in that some of the functions have a hyphen in their
name (for example "linge-newline ()").  Something like "linge_newline
()" should be detected correctly.  If I'm not mistaken, POSIX requires
that shell function names only contain alphanumeric characters or an
underscore; support for hyphens could be a Bash extension.

One way to fix the issue could be to extend the
sh-imenu-generic-expression alist in sh-script.el with a specific regexp
for bash that accounts for hyphens (and any other character that Bash
may support in function names).

It would help me a lot if I can see all supported bash function names in the speedbar.
Currently this is slowing me down when going through the code base.
