This looks like color codes...

The pager (and the attached terminal emulator) should be able to
convert those codes (Escape, [, code sequence) into something
meaningful, usually a change of display attributes such as color,
inverse, underlined (or whatever the terminal supports). In your
case, those are displayed as-is. Standard FreeBSD installations
usually display them as desired:
-setup_dirs() <--- red text
+setup_dirs2() <--- green text
Note that "ESC" is wrong (or probably just a display replacement
for a non-printable character): The character has to be the ESC
code (ASCII #27 or 0x1b), as seen here:
00000000 1b 5b 33 31 6d 2d 73 65 74 75 70 5f 64 69 72 73 |.[31m-setup_dirs|

00000030 29 1b 5b 6d 0a |).[m.|
Maybe your input data got mangled somehow and the ESC character
replaced by the string "ESC", just as hexdump represents it as
a "." in the ASCII output column?
