Wang, Jian J 701e8cc29a MdePkg/BasePrintLib: Fix incomplete print output 
This is caused by previous patch which tried to fix string over-read,
which breaks UEFI menu rendering: the following

/------------------------------------------------------------------------------\
|                               Device Manager                                 |
\------------------------------------------------------------------------------/

is rendered as

/\
|                               Device Manager                                 |
\/.0                                                 2.00 GHz

(the spurious digits are SMBIOS data from the home screen)

The problem appears to be that the CHAR16 value of BOXDRAW_HORIZONTAL
equals 0x2500, which means that testing ArgumentString[] != '\0'
(which tests the low byte only) will yield FALSE and terminate the
loop prematurely.
