[vlc-devel] [PATCH 4/7] config/help: only print variable range if explicitly set

[Filip Roséen]

Unless a module has specified their own range for a certain variable,
the ranges for an integer is always [ INT_MIN, INT_MAX ], and float [
FLT_MIN, FLT_MAX ]. Printing out these ranges explicitly shall not
happen unless a module has specified some other range for a variable.

These changes addresses the above.
