We should use the _print_ascii_file_h function at more places in os_linux.cpp . The function can print a header and an ASCII file which is done a few times e.g. in the hs_err file output .
This also changes the output slightly.
now the output looks like :

/sys/kernel/mm/transparent_hugepage/enabled :
[always] madvise never
/sys/kernel/mm/transparent_hugepage/defrag (defrag/compaction efforts parameter) :
[always] madvise never

/proc/sys/kernel/threads-max (system-wide limit on the number of threads) :
1032335
/proc/sys/vm/max_map_count (maximum number of memory map areas a process may have) :
2147483647
/proc/sys/kernel/pid_max (system-wide limit on number of process identifiers) :
81920


before we had more blanks :
/sys/kernel/mm/transparent_hugepage/enabled:
[always] madvise never

/sys/kernel/mm/transparent_hugepage/defrag (defrag/compaction efforts parameter):
[always] madvise never


/proc/sys/kernel/threads-max (system-wide limit on the number of threads):
1032335


/proc/sys/vm/max_map_count (maximum number of memory map areas a process may have):
2147483647


/proc/sys/kernel/pid_max (system-wide limit on number of process identifiers):
81920
