menuconfig: Add Save/Load buttons
If menuconfig have Save/Load button like alternative .config editors, xconfig, nconfig, etc.We will have a obvious benefit when use menuconfig just like when we use others, we can Save/Load our .config quickly and conveniently. This patch add the Save/Load button for menuconfig. [remove trailing space while at it for below line: "*) Formerly when I used Page Down and Page Up, the cursor would be set" ] Changes: V1-V2: 1:use PATH_MAX instead of hard code suggested by Yann E. MORIN 2:drop the spurious empty-line removal suggested by Yann E. MORIN V2-V3: 1:ajust buttons position well centered reported by Yann E.
