bug#6158: bug in hideshow (trunk)

[Theodor Rascanu]

Hi all,

I guess I have found a the bug in the hideshow package:

Assume the following c++ code:

inline int round_to_next_power2(register unsigned int x){
  //if(x!=32){
  x--;
  x |= (x >> 1); 
  x |= (x >> 2);
  x |= (x >> 4); 
  x |= (x >> 8);
  x |= (x >> 16);
  return x + 1; 
  //}
}

Ok this example do not make much sense programming wise but it shows the probelm:
Hiding this function will not work. 
Having the cursor somewhere inside the function outside the commented
lines and trying to hide it (i.e. by C-c @ C-c) will produce the following:

inline int round_to_next_power2(register unsigned int x){
//if(x!=32){... }

Attached is a patch producing the expected behaviour:
inline int round_to_next_power2(register unsigned int x){... }

Greetings,
Theodor
