[Geany] utils_strtod, invalid_test + patch

[Pierre]

Hello,

A little fix fpr utils_strtod. It should use integer if it needs to
test values lower than 0 (<= 0 incl.). A better fix would be to use
the start address :)

Patch again svn head attached (with some other sanity checks).

Cheers,
--Pierre
