Re: Q on global/gtags with rust codes

Additional information.

It looks GPATH and GRTAGS are created correctly, but GTAGS are not....

This is true with and without modification of 
/usr/local/share/gtags/script/pygments_parser.py.
This is true with the latest global version(6.6.10) and old version(6.6.7).

===========================================
$gtags -d GPATH
  __.NEXTKEY     2
  __.VERSION      __.VERSION 2
./main.rs       1
1       ./main.rs

$gtags -d GRTAGS
  __.COMPACT      __.COMPACT
  __.COMPLINE     __.COMPLINE
  __.COMPNAME     __.COMPNAME
  __.VERSION      __.VERSION 6
String  1 @n 5
calculate_weight_on_mars        1 @n 10,4
input   1 @n 5,2,2
io      1 @n 1,6
main    1 @n 3
mars_weight     1 @n 10-1
new     1 @n 5
parse   1 @n 9
println!        1 @n 4,7
read_line       1 @n 7
std     1 @n 1
stdin   1 @n 7
trim    1 @n 9
unwrap  1 @n 7,2
weight  1 @n 9-1,4-1

$gtags -d GTAGS
  __.COMPNAME     __.COMPNAME
  __.COMPRESS     __.COMPRESS ddefine ttypedef
  __.VERSION      __.VERSION 6
