execve.2: execve also returns E2BIG if a string is too long

The execve syscall returns -E2BIG in 3 cases: - The total length of the command line arguments and environment is too large. - An argument or environment string is longer than MAX_ARG_STRLEN. - The full path to the executable exceeds MAX_ARG_STRLEN. Spell out all 3 cases in the -E2BIG section. Signed-off-by: Rik van Riel <[email protected]> Suggested-by: Matthew House <[email protected]>
