hush: make getch/peek functions directly called
Indirect calls are more difficult to predict.
Unfortunately, on x64 direct call is 5 bytes while indirect "call (reg+ofs)"
is 3 bytes:
function old new delta
i_getch - 82 +82
i_peek - 63 +63
parse_stream 2531 2579 +48
parse_dollar 771 797 +26
parse_redirect 296 321 +25
add_till_closing_bracket 408 420 +12
encode_string 256 265 +9
i_peek_and_eat_bkslash_nl 93 99 +6
add_till_backquote 110 114 +4
parse_and_run_stream 139 141 +2
expand_vars_to_list 1143 1144 +1
static_peek 6 - -6
setup_string_in_str 39 18 -21
setup_file_in_str 40 19 -21
static_get 27 - -27
file_peek 52 - -52
file_get 65 - -65
