Suggestion of enhancement by adding a hyphen to sh-imenu-generic-expression

[James Cherti]

Hello,

While editing a Bash shell script today, I discovered that imenu does 
not include functions with hyphens in their names.

While it is true that sh does not allow hyphens in function names, Bash 
does permit them.

My suggestion is to add a hyphen '-' to the sh-imenu-generic-expression 
(sh-script.el) regular expression to make imenu include these functions,
