[Patch, Fortran, committed] Init a variable

[Tobias Burnus]

Found with the Coverity scanner. It also complains about the 
fall-throughs. Either the comment will silence the warning* or at least 
it helps human reviewers.

Committed as Rev. 197969 after build+regtesting on x86-64-gnu-linux.

(* Well, one can also silence the Coverity diagnostic for that spot.)
