I have confirmed the bug. Thank you.

Could you write a description about this variable for the
CONFIGURATION section of gtags(1)?  Could you explain the format of
'ctags-gtags.conf'?

Should we use a file? How about putting the contents of the file
directly into a variable (may be 'ctagsopt')?

[gtags.conf]
+------------------------------
|:ctagsoptfile=$sysconfdir/ctags-gtags.conf:

[$sysconfdir/ctags-gtags.conf]
+------------------------------
|XX@XX

|
v

[gtags.conf]
+------------------------------
|:ctagsopt=XX@XX:

I'm not sure what you are talking about.
What are '--option' and '--option-maybe'? Which command's options?
