I have seen a French initialization file with

+title=is something with white spaces

This problematic for me, since I am used to the habbit to never have any
white space in proj.4 statements. Example of the french file follows:

<FANGA84> +title=MOP84 (Fangataufa 1984) +proj=geocent +towgs84=150.5700,158.3300,118.3200 +a=6378388.0000 +rf=297.0000000000000 +units=m +no_defs <>

Better would maybe be to put it like:

+title=<something between some markers with white spaces in it> +etc.....
