In previous patches, extern was mechanically removed from function declarations without care to formatting, causing parameter lists to be misaligned. Manually format changed sections such that the parameter lists should be realigned. Viewing this patch with 'git diff -w' should produce no output.

|
|
* - sha1: the hash to search for
|
|
* - fanout_nbo: a 256-element array of NETWORK-order 32-bit integers; the

* first byte is less than or equal to i

|
|
* - stride: distance between two consecutive elements in table (should be
|
|
* GIT_MAX_RAWSZ or greater)
|
|
* - result: if not NULL, this function stores the element index of the

|
* position found (if the search is successful) or the index of the least
