Bastian Bittorf 3ca93f4a4c shellcheck: fix several occurences of SC2034 ...

message:
SC2034: $VARNAME appears unused. Verify it or export it.

most of these are related to the style:
we generate global vars, which are used in other functions.

the var "lexical_url" was really unused (left it as comment)

the travis-check now does not need anymore special flags.
