[PATCH] gnulib-tool: use bold font portably

[Mats Erik Andersson]

Hello there,

when 'gnulib-tool' is listing modules in bold type,
it does so in a non-portable way. FreeBSD displays
this failure, since its printf(1) is not accepting
hexadecimally encoded characters. In fact, the POSIX
manual page printf(1p) mentions octal encoding as
the only valid mechanism. Patch follows.

Best regards,
  Mats Erik Andersson

Subject: [PATCH] gnulib-tool: use bold font portably

* gnulib-tool (func_show_module_list): Change hexadecimal
numbers to octal in BOLD_ON and BOLD_OFF.  The use of hex
encoded numbers as arguments to `printf' is not portable,
and is not claimed by POSIX.  This is the case with FreeBSD.
