`src` parameter for `memcpy` is set to `cextra + begin` but the offset
begin is not taken into account for the calculation of the length that
should be copied.
Fix this by increment the cextra pointer for each skipped whitespace
of the extra parameter.
While at it, rename `end` variable to `cmdline_len`, `command_line`
variable to `cmdline`, remove useless void pointer cast, and use
strlen instead of a while loop to determine the cmdline string length.
