 It seems like parentheses in they key name may not be getting properly
 escaped somewhere. With a small test I'm getting "Invalid path expression"
 and "garbage at end of path expression" error messages at runtime.

 Here's how to reproduce the error... (the files mentioned are attached)


 {{{
 # cat /tmp/bug_parens_in_key_func_file
 some_func() {
  return 1;
 }
 }}}



 {{{
 # cat bug_parens_in_key.aug
 module Bug_Parens_In_Key =
   autoload xfm
   let empty   = Util.empty
   let eol = Util.eol
   let ws = Util.del_ws_spc
   let lbrace = Util.del_str "{"
   let rbrace = Util.del_str "}"
   let func_sig_no_args = /[A-Za-z0-9_]+\(\)/
   let func_body = store /[^}]*/
   let func = [ key func_sig_no_args . ws . lbrace . func_body . rbrace .
 eol ]
   let lns = (empty | func) *
   let filter = incl "/tmp/bug_parens_in_key_func_file"
   let xfm = transform lns filter
 }}}



 {{{
 # augtool ls /files/tmp/bug_parens_in_key_func_file
 error: Invalid path expression
 error: garbage at end of path expression
 error: /files/tmp/bug_parens_in_key_func_file/some_func(|=|)/*
 error: Invalid path expression
 error: garbage at end of path expression
 error: /files/tmp/bug_parens_in_key_func_file/some_func(|=|)
 some_func()/ = H
 }}}



 Another odd thing worth mentioning is that when I try to reproduce the
 error using a test aug script, either the error doesn't occur or the error
 message is suppressed.


 {{{
 # cat tests/test_bug_parens_in_key.aug
 module Test_Bug_Parens_In_Key =
   let func_file =
 "some_func() {
  return 1;
 }
 "
   test Bug_Parens_In_Key.lns get func_file =
     { "some_func()" = "\n return 1;\n" }
 }}}



 {{{
 # augparse -I bug_parens_in_key.aug tests/test_bug_parens_in_key.aug
 #
 }}}


 No news is actually bad news.
