Possible issue with use of --wrap

[JasonCust]

This is either a lack of documentation (leading to a lack of understanding) or a bug. I have been trying to use the --wrap option for argbash-init but it doesn't seem to have any effect.

$ argbash-init --opt environment --opt name -m full foo.m4
$ argbash-init --pos foobar --wrap foo.m4 -m full bar.m4
$ cat bar.m4
#!/bin/bash

# m4_ignore(
echo "This is just a script template, not the script (yet) - pass it to 'argbash' to fix this." >&2
exit 11  #)Created by argbash-init v2.10.0
# ARG_POSITIONAL_SINGLE([foobar])
# ARGBASH_SET_DELIM([ =])
# ARG_OPTION_STACKING([getopt])
# ARG_RESTRICT_VALUES([no-local-options])
# ARG_DEFAULTS_POS
# ARG_HELP([<The general help message of my script>])
# ARGBASH_GO

# [ <-- needed because of Argbash

# vvv  PLACE YOUR CODE HERE  vvv
# For example:
printf "Value of '%s': %s\\n" 'foobar' "$_arg_foobar"

# ^^^  TERMINATE YOUR CODE BEFORE THE BOTTOM ARGBASH MARKER  ^^^

# ] <-- needed because of Argbash

Expected outcome is the bar.m4 file would include a # ARGBASH_WRAP(...) line but it doesn't. Am I misunderstanding how to use --wrap?

EDIT: I've tried using both --wrap foo.m4 and --wrap foo as the underlying ARGBASH_WRAP says to use the filename stem.
