[Openmcl-devel] ...the sky is falling

[Joakim Sandgren]

again,
in the old version 13560 calling some functions invoke the console.
others go to the document without finding and without invoking the  
console.
and:
all functions that happens to be written in one line without a new  
line are found...

in version 13585 the 2 first cases dont find and dont invoke the consol.

the one line functions are still found...

for whatever its worth...

sincerely
joakim
