[PATCH 3/5] gnulib-tool: small sed optimization.

[Ralf Wildenhues]

* gnulib-tool (func_get_automake_snippet): Merge multiple sed
invocations.

Signed-off-by: Ralf Wildenhues <address@hidden>

Noting that these sed scripts can be merged may not be trivial,
you may believe me that it is alright in this case.  ;-)

I have not timed the impact of this.

Cheers,
Ralf
