The Bash Reference Manual (http://www.gnu.org/s/bash/manual/bash.html#Special-Parameters) says:

At shell startup, [$_ is] set to the absolute pathname used to invoke the shell or shell script being executed as passed in the environment or argument list. [...]

However, with GNU bash, version 3.2.39 a simple script (named 'a'):

echo "$_"

prints './a' when invoked as './a'. According to the above excerpt, should it not print an absolute path to 'a' instead?
