Subject: include/log: Don't mangle whitespaces

include/log: Don't mangle whitespaces

Because IFS is not set in `_log_write()`, logging functions silently
drop whitespace from the beginning and end of each line.

This commit modifies `_log_write()` to set IFS to the empty string
when invoking `read`, so that whitespaces are not stripped.
