I am following Karl's advice to contact gnulib regarding this. Thank you
for the explanation. I know the bootstrap used by libtool is maintained
on Github. I referenced gnulib-modules/bootstrap [1] in the bug report,
but I should have added in the link for clarity.

I also assumed gnulib would be the correct place to contact for
understanding some design decisions with bootstrap, since it is under
the 'gnulib-modules' namespace. It seems this is wrong though. I will
close this here for now and ask about this issue on Github.

Hi,

It was reported [1] that error messages from a libtool invocation have
additional spaces after the package name before the error message. After
looking into this, it seems that gnulib-modules/bootstrap is the cause.

Here is an example:
libtool:   error: only absolute run-paths are allowed

Here is the relevant code in bootstrap:
```
# func_error ARG...
# -----------------
# Echo program name prefixed message to standard error.
func_error ()
{
    $debug_cmd

    $require_term_colors

    func_echo_infix_1 "  $tc_standout${tc_red}error$tc_reset" "$*" >&2
}


# func_fatal_error ARG...
# -----------------------
# Echo program name prefixed message to standard error, and exit.
func_fatal_error ()
{
    $debug_cmd

    func_error "$*"
    exit $EXIT_FAILURE
}
```

Is there a reason for the extra spacing, or could this be changed?
